General impacts C. argus could cause devastation to freshwater ecosystems of the United States because of its predacious nature, lack of natural predators, high fertility, and adaptability to a wide range of environmental conditions. Where introduced, it could bring disease and harm native organisms. These changes could also hurt local economies dependent on fishing (Courtenay, W., pers. comm., 2003).
